Photo 14: LBBG, May 05 2001, Etaples (NW France).
An advanced second type LBBG in
first summer actively moulting coverts and
scapulars. P1 has been shed, as is common in LBBG by early May.
It shows advanced moult, as can be seen in quite some graellsii/intermedius in spring, both in France and in the Netherlands.
In the lesser coverts, all but two have been moulted to second generation. Active moult is still going on, as can be seen in the carpal edge, where juvenile feathers are visible. The visible median coverts are second generation. In the greater coverts, the inner 10 are second generation, #11 is juvenile, #12 is second generation, #13 and the outer greaters are juvenile. The moult strategy is complex: #1-2 were moulted first, #3-10 were moulted from outside to inside.
One lower scapular is still juvenile.
The tertials are all second generation and the upper three show much abrasion. These tertials were probably moulted already some time ago.
The entire tail has been replaced by second generation rectrices. In the primaries, P1 has been shed recently.
Note the pink base of the bill and note the extensive streaking on head, neck, breast sides and flanks as well.
The pattern on the scapulars and coverts is clearly barred.
For graellsii/intermedius, this is probably the most advanced moult stage possibly in spring (by early May) in first summer. Primary moult can be as far as a shed P4, but regarding really new primaries, May 2001 no graellsii/intermedius showed a fully grown P2 or higher.
